Furnace Maintenance

Why is Furnace Maintenance Necessary?

A Furnace maintenance is necessary for many reasons, but the biggest reasons are to check on all of the operations, the moving parts, and maintain the manufacture warranty of the equipment. Your furnace can still operate and not operate efficiently for you and your household, checking through all operations and making adjustments can make sure that your system is working its best for your comfort. Preventative maintenance (maintenance done before there is failure) can help with potentially replacing parts before they fail completely and leave you without heat in your home. Over the past few years, manufactures of the equipment are becoming more difficult when it comes to the warranty of the equipment. To the point where some manufacturers want to see proof of maintenances being done, and will void the warranty if the equipment has not been maintained for multiple years.

What’s Included

• Flame sensor (clean)
• Igniter (check resistance in ohms)
• Blower motor (test amps and capacitor if applicable)
• Burner assembly (clean)
• Inducer assembly (test amps, capacitor, check drains and tubing if applicable)
• Gas valve (Verify operations, check gas pressure)
• Return temperature (verify incoming temperature)
• Supply temperature (verify outgoing temperature)
• Delta temperature (difference between return and supply)
• Check heat exchangers (look over primaries for cracks)
• Check Secondary heat exchangers (if applicable, checking for blockage in airflow)
• Check and change/clean filter (if they don’t have we can supply)
• Verify electrical (both 120v and 24v)
• Check over wiring (all connections between components and control board)
• Inspect visible duct work around system for seals (if applicable)
• Check applicable accessories (condensate pump, UV, humidifier)
• Check condensate drains when applicable 
• Check static pressure (helps to determine airflow in cubit feet per minute or CFM)
• Verify operations of limits and pressure switches
• Test exhaust for combustion analysis (checking for temperature, CO, and O2 content)
• Verify thermostat operations (run system and go over thermostat functions and operations with you)
